Citrus is considered as one of the most important agricultural products in the world; that increasing its yield and product has attracted global attraction. The present researchhas been designed in the Randomize Completely Design inthe factorial plan in four replications. The main factor was includedsubstrate enriched (PGPR bio fertilizers) and without enriched substrate. Subplot was conventional 5 treatments: 1) control (without chemical fertilizers and phosphate bio fertilizer), 2) seedlings’ root inoculated with Pseudomonas putida 41; 3) phosphate fertilizer based on soil test; 4) phosphate chemical fertilizer, 25% less than soil test + Pseudomonas putida 41 and 5) phosphate chemical fertilizer, 50% less than soil test + Pseudomonas putida 41  in 4 replicates .Overall 40 pots have been tested. The results analysis with MSTATC software using Duncan test showed that wet and dry weight of root and shoot and the P, Fe, Zn concentrations and the lateral branches number increased in substrate enriched in compared with control.  The growth parameters include; rootstock length, scion length, rootstock diameter and scion diameter increased in different treatments of pseudomonas and phosphorus fertilizer.
